There is no absolute predictor of fertility.
But we can test & track your hormones, and that's a good start.
Grip helps you exclude the most common reasons why women struggle to conceive, just like a fertility clinic would.

"At 32, I am really starting to think about the idea of having children, yet I have no idea whether I can even have them. Some friends around me have been trying to get pregnant for a long time. We are told to be careful *not * to get pregnant, but we're never educated about the possibility of not being able to conceive, or how to make sure that you can.
I would just love to understand my body that bit more. That’s why I am so excited that Grip exists - I recommend this to all of my friends!"

""I'm not planning for children yet, but I was keen to know more about what to expect when the time comes.
Grip has helped me find out more about my body as well as how my fertility is affected, so I can now go to my GP with questions I wouldn't have been aware of otherwise. I feel much more prepared and knowledgeable for the future now."
Product Analyst, Cambridge, UK
"I am in a very demanding career, which can sometimes take over, so it’s nice to know some information about my fertility.
I chose Grip because it's easy to use and very accessible. Within the comfort of my own home, I can find out about my fertility status, or at least if I have a good chance of ovulating each month so I can start planning my family."

How Grip works
You take the test on your terms, from the couch
01. Get the kit
02. Collect your
03. Lab analysis
04. Video call our doctors
Answer a few questions, we'll customize your test based on your birth control.
So yes, you can take the test if you're on birth control.
Prick your finger, collect about 10 drops (0.5ml) of blood, and pop your sample in the mail. That's it!
Our lab, the same one that fertility clinics use, analyses your blood sample.
Our lab is ISO15189 certified, the highest possible medical certification.
Your results are just the start. Most hormonal imbalances are easily treatable, as long as you have time. Our doctors will make a (free) plan with you, and you can ask all your questions in our closed chat group.
How we protect your data.
We understand how sensitive your information is, and we work very hard to keep everything as safe as possible. The lab uploads your results to a special medical cloud, and the only way that we can see your report is through 2-factor authentication. Only medical professionals have access to your report.
We are GDPR compliant, which means that we won't store any of your data unless you give us explicit permission to do that. Most women want us to store their information so that if you test again next year, we can easily compare your results.
We ask everyone to opt in to giving us an anonymised version of your results for fertility research, but if you don't want to participate, you, of course, don't have to.
